WebApr 12, 2024 · A local thermal equilibrium (LTE) model is used to fit synthetic spectra to the detected lines and to derive the column densities based solely on optically thin lines. Results. The H 2 S and OCS column densities span four orders of magnitude across the sample. The H 2 S/OCS ratio is found to be in the range from 0.2 to above 9.7. WebFitness for purpose of testing may also be performed using reduced partial pressures of hydrogen sulfide and for durations of up to 30 days. Following the exposure period, the specimens are metallographically prepared, optically examined, and any cracks are measured and the following ratios reported: CSR (Crack Sensitivity Ratio)
